IMPROVEMENT IN CARRIAGE-SPRINGS.

Specification forming part of Letters Patent No. 199,646, dated January29, 1878; application filed December 24, 1877.

To all whom it may concern Be it known that we, JACKSON W. HEWITT I andWILLIs J. HEWITT, of the city of J ackson, county of Jackson, and Stateof Michigan, have invented a new and useful Improvement in Carriage andBuggy Springs, which improvement is fully set forth in the followingspecification and accompanying drawing, in which-- Figurel is anisometrical perspective. Fig. 2 is a plan; and Fig. 3 is a part of theside elevation, to show improved attachment.

Our improvement relates to springs for carriages, wagons, and the like,in which auxiliary springs are employed in connection with half-ellipticside springs, in order to prevent the sagging of the body and springswhich the unequal distribution of weight in the vehicle is apt to cause;and in carrying out our invention we form the two short springs,intermediate of the side half elliptic springs, and the cross-bars ofthe frame, with angular ends or dependent brackets, all in one piece,and arranging the same substantially as hereinafter more fully set forthand claimed.

Referring to the accompanying drawing, A A represent the cross-bars ofthe frame; E E, the angular ends or brackets thereof; and B B, the shortauxiliary springs, which are connected with the loops 0, as shown. Theseloops are connected with the rear axle-tree G by means of hangers D, soas to counteract the weight, which is usually in excess in the rearportion of the body of the vehicle.

These cross-bars A A and short springs B B are formed into a frame inone piece, with. a flat surface, upon which the body or frame is boltedand secured in position. The way in which we can form this frame is bywelding to gether the springs and bars. In this way all liability of thedisarrangement of the frame and springs is avoided, and also the use ofbolts and nuts for connecting the same, and a strong, perfect frame,whereoh the body may be seated, is obtained.

Fig. 3 shows the same in position, with the side half-elliptic springsF.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is-

The short auxiliary springs B B, intermediate of the side half-ellipticsprings, and the cross-bars A A, with angular ends, the same beingformed into a frame in one piece, with a fiat surface, substantially asherein shown'and described, and for the purpose specified.
